DIRECT ANSWER: The Robinson projection is a compromise world map, designed by American geographer Arthur H. Robinson in 1963, that deliberately sacrifices perfect accuracy in area, shape and distance in order to produce a map that simply "looks right" to the human eye.
What is the Robinson projection?
The Robinson projection is a way of flattening the round Earth onto a rectangle of paper or a screen. Every world map has to solve the same impossible problem: you cannot peel a sphere flat without stretching, tearing or squashing it somewhere. Different projections make different bargains about where that unavoidable error goes. The Robinson projection makes a very particular bargain — it refuses to be perfect at any one thing, and instead spreads the error thinly across the whole map so that no region looks too badly wrong.
Because of this, cartographers call it a compromise or pseudo-cylindrical projection. It preserves no single geometric property perfectly — not area, not shape, not distance, not direction — but it keeps all of them reasonably close to the truth. If you want a deeper primer on how flattening the globe works in general, see our guide on what a map projection actually is.
Who created it, and why?
Arthur H. Robinson developed the projection in 1963 while working at the University of Wisconsin. The mapmaking company Rand McNally had asked him for a general-purpose world map that would look attractive and natural for atlases and classrooms, rather than one optimised for navigation or scientific measurement.
Robinson's approach was unusual. Most projections start with a mathematical formula and accept whatever visual result that formula produces. Robinson worked backwards. He decided how he wanted the finished map to look, and then found the numbers to match.
Designed by eye, not by equation
Rather than deriving his map from a single equation, Robinson defined it using a lookup table of coordinates. He adjusted the spacing of latitude and longitude lines by hand, tweaking the values repeatedly until the continents looked correctly proportioned and the overall map felt balanced. Only afterwards did he interpolate smoothly between those tabulated points to fill in the rest.
He described the result as an "orthophanic" projection — a coined word meaning "right-appearing." The goal was the best-looking map, not the best-measuring one. This artist-first philosophy is why the Robinson projection feels so familiar and comfortable: it was literally tuned to satisfy the human eye.
What the map looks like
You can usually recognise a Robinson projection at a glance by a few distinctive features:
- An oval, elliptical outline. The map is not a hard rectangle; its top and bottom edges curve gently, giving the world a rounded, globe-like silhouette.
- Straight, horizontal parallels. Lines of latitude run as straight horizontal lines across the map, which keeps north-south orientation intuitive.
- Curved meridians. Lines of longitude bow outward, curving toward the poles but never quite meeting — unlike a globe, where they converge to a single point.
- Poles drawn as lines, not points. Because the meridians never converge, the North and South Poles are stretched into horizontal lines across the top and bottom of the map.
If the words parallel and meridian are new to you, our explainer on latitude and longitude covers the grid every projection is built on.
Where does the distortion go?
No compromise projection escapes distortion — it only manages it. On the Robinson map, the trade-offs break down roughly like this:
- Area: Moderately distorted. The polar regions are inflated, but only by roughly a factor of two — noticeable, yet far gentler than the extreme stretching seen on some other maps.
- Shape: Most faithful in the mid-latitudes, where most of the world's population and landmass sit. Shapes become progressively more stretched toward the edges and the poles.
- Distance and direction: Reasonably accurate across the map as a whole, though never exact between any two specific points.
The key idea is balance. Because Robinson tuned the map so that no property is perfect and none is disastrous, the errors tend to cancel out visually. A student glancing at the map gets a broadly honest impression of the world — the continents are about the right size relative to one another, and their outlines are recognisable.
Robinson vs Mercator vs Winkel Tripel
The best way to understand a compromise projection is to compare it with the alternatives it sits between.
The Mercator projection
The Mercator projection, created by Gerardus Mercator in 1569, is a conformal cylindrical map. It preserves angles and local shapes perfectly, and it renders lines of constant compass bearing (rhumb lines) as straight lines. That made it invaluable for sea navigation, and it is why Mercator still underpins most online slippy maps today.
The price is severe area distortion at high latitudes. On Mercator, Greenland appears roughly the size of Africa, even though Africa is about fourteen times larger. The Robinson projection avoids this dramatic inflation entirely — its polar exaggeration is mild by comparison — but it gives up the perfect angles and straight navigation lines that make Mercator useful at sea.
The Gall–Peters projection
At the opposite extreme sits the Gall–Peters projection, which is equal-area: it shows every country at its true relative size. That honesty about area comes at the cost of badly distorted shapes, with continents appearing stretched and elongated. Robinson refuses both extremes, splitting the difference between Mercator's accurate shapes and Gall–Peters' accurate areas.
The Winkel Tripel projection
The Winkel Tripel projection is Robinson's closest cousin — another compromise map designed to minimise three kinds of distortion at once (its German name, Tripel, refers to that triple goal). In practice, Winkel Tripel achieves slightly lower overall distortion than Robinson, which is why it eventually replaced it as the reference world map of choice for many publishers.
Rise and retirement: the National Geographic era
The Robinson projection's biggest moment came in 1988, when the National Geographic Society adopted it as the standard for its reference world maps. It replaced the Van der Grinten projection, which the Society had used since 1922 and which exaggerated polar areas far more heavily.
For about a decade, the Robinson projection was among the most-seen world maps on Earth, hanging in classrooms, offices and living rooms wherever National Geographic maps reached. For a generation of students, "the world" simply looked like the Robinson projection.
Then, in 1998, National Geographic switched again — this time to the Winkel Tripel projection, citing its marginally better balance of distortions. The change was evolutionary rather than revolutionary: both are compromise maps chasing the same goal, and to a casual viewer they look very similar. Robinson had simply set the standard that Winkel Tripel refined.
When should you use the Robinson projection?
The Robinson projection is at its best for general-purpose reference and educational maps — the kind you want to hang on a wall, print in an atlas, or use to give an overall sense of how the world is arranged. Its strengths are visual balance and familiarity; its weakness is that it should never be used for precise measurement, navigation, or any task that depends on exact area or angle.
A quick rule of thumb:
- Navigation or web mapping? Use Mercator, whose straight compass lines and preserved angles are built for it.
- Comparing the true size of countries? Use an equal-area projection like Gall–Peters.
- A handsome, honest, all-round world map? Reach for Robinson — or its successor, Winkel Tripel.

The takeaway
The Robinson projection is a reminder that there is no such thing as a perfect flat map — only thoughtful compromises. By choosing to be "right-appearing" rather than mathematically exact in any single dimension, Arthur Robinson created a map that felt natural to millions of people and shaped how a generation pictured the planet. It is not the tool for a navigator or a surveyor, but as a picture of the whole world, it remains one of the most elegant balances cartography has produced.
